“This is a week of heroes in New York,” Police Commissioner Ray Kelly said.

The incident began at 12:20 p.m. when Timothy crawled onto the fire escape outside the fifth-floor apartment of his babysitter, Carole Baldwin, 50.

Baldwin told cops she opened a window to smoke and then stepped away to go to the bathroom.

Timothy apparently fell through a gap to the fourth-floor escape, gashing his head but grabbing onto a railing. The tot was screaming “Help me! Help me!” as he clung to the railing over 40 feet above the street.

Gonzalez, who lives across the street, was with Nevarez when they spotted the toddler.

“He was hanging on for dear life,” said Gonzalez, a mechanic. “We ran over and stood underneath so we could catch him.”

Margaret Somuah, 53, a home attendant taking care of an elderly woman on the fourth floor, heard the commotion, looked out the window and saw Timothy losing his grip from the railing.

“As soon as I opened the window and tried to catch the baby, he fell,” Somuah said.

“Oh, my God!” she exclaimed.

Timothy, wearing only a T-shirt and sweat pants, hit some tree branches before landing directly onto Nevarez, who fell backwards. “It knocked me out of my shoes,” he said.

But luckily Gonzalez – a father of six who was home yesterday because one of his sons was sick – was standing inches away.

“The force of the kid knocked me to my knees and he fell out of my hands” – but landed on the ground gently, Gonzalez said.

He opened his jacket to wrap the boy and waited until an ambulance took Timothy to St. Barnabas.

“I was scared,” the boy told relatives.

Gonzalez said he acted instantly when he realized Timothy’s plight.

“I just knew that baby was not going to hit the ground,” he said

Before the accident, Timothy told his mother he was going to be a superhero.

“This morning I want to be Superman,” he said. Then he added, “I wanna be Spider-Man.”

It was the second time Timothy was “a miracle baby,” uncle Jose Monche said, because he was born three months premature and weighed only 1½ pounds at birth.
